Hi Vineet S,

Thanks for reaching out to Microsoft Q&A.

Can you try with @trigger().startTime or @trigger().endTime ? pls check and let me know, meanwhile I will check and add up anything if i get.

Hello Vineet S,

I see in your JSON, "type": "ScheduleTrigger", but you have mentioned tumbling windows trigger.

If this is correct, please update the type as Tubmingwindowtrigger

from the below thread:

trigger().outputs.windowStartTime is only valid when the pipeline is triggered through TumblingWindowTrigger.

I hope this answers your question. Please let me know if you still see any issues.
